Did you see the awesome Click and Drag comic at xkcd? I made it into an .mc file which is readable in Golly. :) For best experience, resize the window to the Click and Drag panel size and keep the zoom level to 1:1. Download .zip file It's 7.86MB. It's about the size of the original Click and Drag P...

After a lot of work and searching, I found the most possible, useful and basic reaction that could create the glider salvo that could create long crystals made of plusses: x = 39, y = 46, rule = 345/2/4 23.2C$23.2B$23.2A14$2.A$.3A.A$2A.2AB$.3A.C$2.A$12.2C23.A$12.2B22.3A$ 12.2A4.ABC16.A$18.ABC2$12.2...

After some more searching, I've found a much more basic, but messier, but I believe there's a chance to clean it up: x = 25, y = 22, rule = 345/2/4 .A$3A$.A6$18.CBA$18.CBA$17.CBA$16.CBA$21.2A$20.A2BA$20.B2CB$19.AC2.CA $19.B4.B$19.C4.C2$19.2A$19.2B$19.2C!

EDIT: A different soup which produces a tumbler in (I think) an entirely different way to the one a few posts ago: x = 20, y = 20, rule = 23/3 2obo3b4o2bo2bo$2ob2obob2o3bo2bob2o$b3ob2ob2o2bob3o$6b2ob2o2b2o 4bo$obob3ob2ob6o$b2ob5o2bo4b2o$bo3bo2b3ob2ob2o$o3bobo2b9obo$2o bobo4b2o5b2o$2o2b2obo2bo2bobo$...

Okay, let me explain: What does this do? This is a device which is used in a metapixel. A metapixel is a pattern that it can be used as a single cell of another rule. (See the Hashlife folder in Golly's Pattern folder - you will find OTCAmetapixel, a metapixel in Life.) This device checks the number...

Here's a simpler way to control a construction arm using only one block and no more than 4 gliders on each operation: x = 27, y = 42, rule = Serizawa .A10.A10.A3$11.B10.B$10.A.A8.A.A2$3.B11.B$2.A.A9.A.A8.A$24.ABA$24.A.A 4$.B$A.A7$.A10.A3$2.B8.B$.A.A6.A.A2.A$14.ABA$14.A.A$4.A$3.ABA$3.A.A5.
